Banner QS18 replacement and cross-reference check: send the exact model or label photo to compare sensing mode, range, PNP/NPN output, connector, price and lead time.
Banner QS18 is a compact rectangular photoelectric sensor family. A safe replacement starts by identifying whether the installed sensor is diffuse, retro-reflective, through-beam or background suppression, then matching PNP/NPN output, light-on/dark-on logic, range, connector and mounting.

Original brand names are used only for technical cross-reference and compatibility discussion.
| Parameter | Original Model | J&V Alternative | Check Before Order |
|---|---|---|---|
| Original Model | Banner QS18 series photoelectric sensor | J&V rectangular photoelectric sensor | Send full model code and label photo |
| Output | PNP, NPN, relay, two-wire or analog depending on original part | Matched output selected before quotation | same function, matched housing and wiring |
| Supply Voltage | Typically 10-30 VDC or machine-specific range | Voltage range matched to machine input | Measure panel voltage if the old label is unclear |
| Mechanical Fit | Housing, thread, bracket or slot profile from original series | Closest J&V housing and mounting accessory | Confirm length, face type and cable exit |
| Application | photoelectric sensor | general replacement | Confirm target material, distance and environment |
This is real J&V photoelectric product evidence, not a claim that an E3Z housing directly replaces every Banner QS18 model.
| Shown J&V family | E3Z rectangular photoelectric sensors |
|---|---|
| Visible example variants | E3Z-D62, E3Z-D81, E3Z-D82 and E3Z-R61 |
| Relevant capability | Diffuse and reflector-style photoelectric product routes |
| QS18 check required | Optical mode, sensing range, output, light-on/dark-on, connector and bracket |
| Cross-reference rule | The full QS18 suffix and installed photo decide whether a direct or sample-test route is appropriate |
Compatibility note: J&V confirms the original model label and machine conditions before quotation. A product-family photo alone is not compatibility proof.
J&V Automation does not publish placeholder certificates or unmatched test reports. Documents are linked only after the model coverage and publication permission are checked.

Most replacement inquiries start with an old label, a blurry machine photo or a partial model number. J&V Automation narrows the risk by checking the electrical interface first, then the mechanical fit and real application conditions.
J&V connects GEO answer pages with the public product catalog, PDF catalogs and live model search.

It is a J&V Automation alternative selected after comparing the original Banner QS18 series model code, wiring, voltage, range and mounting. It should not be chosen by brand name alone.
Usually yes when the output, sensing distance, housing and environmental rating match. Critical safety or precision applications need a sample test first.
Send the complete model number, label photo, installed photo, quantity, destination country and any PLC input requirements such as PNP or NPN.
